Abstract
. Amperometric i-t measurement supports the finding of CV measurement and showed good sensing ability of the electrode ZnO/CNO nanocomposite material for up to 40 days. The enhanced electrocatalytic activity of the ZnO/CNO nanocomposite is explained due to the synergetic effect of both ZnO and CNO. Our findings suggest a high potential for ZnO/CNO nanocomposite-based glucose biosensors, which could be further utilized to develop noninvasive skin-attached sensors for biomedical applications.
